I guess on some systems, size_t might be 64 bits, so how can I tell from Java in
a portable way?

I believe it will be IntByReference since the comment says it's a length.

Thanks!

prototype:

int nc_inq_att(int ncid, int varid, const char *name, nc_type *xtypep, size_t *lenp);

example:

int status; /* error status */ int ncid; /* netCDF ID */ int rh_id; /* variable ID */ nc_type vr_type; /* attribute types */ size_t vr_len; /* attribute lengths */

status = nc_inq_att (ncid, rh_id, "valid_range", &vr_type, &vr_len);

thanks for any help, very cool package!
